THE Mikado is believed to be the most frequently performed theatrical work in the english speaking world, the most popular Gilbert and Sullivan opera and aguably, the most popular opera ever written. Now Plymouth Gilbert and Sullivan Fellowship are to stage this work later this month, when they take to the stage of the city's Athenaeum Theatre from April 17. The origins of The Mikado have become such a popular story it was made into a movie in 1999 by Mike Leigh, starring Timothy Spall and Jim Broadbent. The Plymouth Gilbert and Sullivan Fellowship's forthcoming production will be sure to be full of the vivacity and enjoyment that audiences have come to expect from this award-winning company. Produced by the award-winning team of Alan Spencer and Carole Wilson, the Fellowship has now welcomed Jonathan Watts as its musical director. The traditionally set production includes well known faces in its principal line up — Kim Willcocks as Yum-Yum, working alongside Stuart Whitehead as Nanki Poo. Peter Preston returns to the stage as Ko Ko, along with his right-hand men, Peter Clement and Gareth Davies. The Mikado is to be performed by Rod Hunt, with Helen Mallet taking the role of Katisha. Helen will be travelling from Cardiff to rehearse and perform with the Fellowship, as she is currently studying voice at the Royal Welsh College of Music. The Mikado by Plymouth Gilbert and Sullivan Fellowship runs from April 17 until April 21. Performances are at 7.30pm, with a Saturday matinee at 2.30pm. Tickets can be obtained from the Athenaeum box office on 01752 266104, and are priced £10 with concessions available.
